Safety Requirements::
This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures
and special safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to
any other climatic conditions than those stated under "Specification".
2. Make it a rule to always disconnect voltage source and device before opening it up. The entire device and its
connection have to be fingerproof after installation.
3. Standard regulations for operation and sefety for electrical light and heavy current euipment have to be
observed, with particular attention having to be paid to national regulations (e.g. VDE0100).
4. If device is to be connected to other devices (e.g. via serial interface) the circuitry has to be designed most
carefully. Internal connection in third party devices (e.g. connection GND and earth) may result in not-
permissible voltages impairing or destroying the device or another device connected.
5. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be
marked accordingly to avoid re-starting.
Operator safety may be a risk if:
- there is visible damage to the device
- the device is not working as specified
- the device has been stored under unsuitable
In case of doubt, please return device to manufacturer for repair or maintenance.
6. Attention: Do NOT use this product as safety or emergency stopping device, or in any other application
where failure of the product could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and material damage.
Connection information:
The interface-converter can supply the specifieded numbers of
EASY
BUS
standard loads (max. 64 pieces) .
Please note that some
EASY EASY EASY EASY EASY
BUS BUS
BUS BUS
BUS
-modules have a higher bus load as the standard load!
Please notice the corresponding specification in the module manual.
Bus loads of some
EASY
BUS
modules:
EASY
LOG
-family: 2
EASY
BUS
standard loads
EBN : 2
EASY
BUS
standard loads
EBHT, EBT, EBH : 1.5
EASY
BUS
standard loads
GIA20EB, GIR2002 : 1
EASY
BUS
standard load
When connecting the modules keep in mind that the sum of all bus loads of the modules must not exceed the
maximal allowed number.
Worked sample:
1) Connection of 20
EASY
LOG
, 12 EBHT and 10 GIA20EB:
20 * 2 + 12 * 1.5 + 10 * 1 = 40 + 18 + 10 = 58 standard loads (42 devices) => connection is possible
2) Connection of 30
EASY
LOG
, 5 EBN:
30 * 2 + 5 * 2 = 60 + 10 = 70 standard loads (35 devices) => EBW64 are overloaded!
3) Connection of 64 GIA20EB or GIR2002:
64 * 1 = 64 standard loads (64 devices) => connection is possible
